摘要：
CompactPCI总线是一种兼容性强、功能全面的计算机总线,目前已被工业自动化和测量领域接纳并得到广泛地应用。为解决进口CompactPCI总线开关模块价格昂贵,使用和维修成本高的问题,以PCI9054作为总线桥接芯片,FPGA和大电流达林顿晶体管为开关阵提供译码驱动,实现了CompactPCI总线开关模块的国产化。CompactPCI总线开关模块可广泛应用于自动测试领域,同时其总线接口和驱动电路具有很好的通用性、扩展性,可作为其他CompactPCI总线类模块的基础电路加以应用。

Abstract: For its strong compatibility and comprehensive function, CompactPCI bus has been accepted and widely used in the industrial automation and automation testing industry, but the imported CompactPCI bus switch module is very expensive, and its running and maintenance cost are expensive too. So it is important to design domestic CompactPCI bus switch module. One of such module has been designed using PCI9054 as bus bridge chip, FPGA and the large current Darlington transistor as decoding driver for the switch array. The developed module can be widely applied to the field of automation testing, and the generality and extendibility of its interface and driving circuits are very well so that they can be used as the basic circuit blocks of other CompactPCI bus modules.
